I wanted to make a feeder tank cheap then decided to start netting minnows when spring gets here and thought I'd make a quarantine tank also.
So I stole the idea from midnight but adapted it a little to help aeration and water movement.
Here are the parts used: 2" PVC, 3/4" PVC, Bushings, Elbows, Cap, adn Scrubbies

I drilled two rows of holes with a 1/8" bit in the 3/4 PVC

Here is a shot of the 18 gallon quarantine tank already done

Close up of the outlet
